To ail whom t may concer/n.:

Be it known that l, meer E. Kerne, a citizen of the United States, residing at Philadelphia, in thecounty of Philadelphia. L

and State 'ot Pennsylvania, have invented certain new and useful improvements in Hammers, of which the following is a speci- This invention relates to hammers provided with renewable faces; and it consists in tlie novel construction and combination of the parts hereinafter fully described and claimed whereby the striking face of the hammer is attached to tire head,

ln tlie drawings, Figure i is a side view of a. hammer constructed accordin` to this invention. and showing portion of it in eee-tion. Fig., 2 is a side view oi a portion the hammer head, partially in section and elica/'ing tire Enc-e and. aclret in a eosition to be connected to 3 is a longitadinai section through tlie face and its jaclrefl; detached from tice head. Fig el is end o tlie same, 5 is also a i ngitndinal section shows a inodioetion oi? time iace and its @ocio-et.

lianinier liead 8 is formed oil any snit liard metal, and it a liandle 9 sa cured to it in any approved way. The hammer head preferably nas a striking tace 1U each lfend, ont as botli. are alike the vdeecription will lo'e'res'ricted to one enda The hammer head laas a cylindrical projection l2 arranged in line its anis, and having a circumferential groove lll vvliere it joins onto the head. A shoulder l is formed on tire liead around tine projection, and. this shoulder has a concave recess l5 which merges into time lcott/oin ezt the groove lll. The striking; ace l0 of tlie loam mer is preferably formed of soit material, lead or a similar soft and dnctile metal loeing preierainly used. in carrying out this invention the hammer :tace may "oe made o lead, brass, coroner, raw liide, liber, and other soit materials,

'When the tace l0 is formed oi lead, it is provided' with cylindrical .slianlr 18 which llas a c lindrical socket 19 which ts overthe progection 112 on the' hammer head: The shank is smaller in diameter; than theiiace, so that a shoulder 20 is Y:.'tornaed vat their pointfo jun ion. Longitiidinallngs 21er@ provided cn the shank, and are arranged at equal 'distances apart. cylindrlcal steellijacket 22 incloeee the shank 18,' an

fshanlfliaving a socket w eine' one end of it bears'against the shoulder 2U. The end portions of the lugs .2i pro'ect from tile other end ofthe jacket, and t e jacket isermanently secured to the shank.

tie face is slid over the projection l2 as shownin Fi. 2. liie ends of the lugs are then driven ard into the concave recess so that they are vbent around into engagement with the groove 14, asfsliovvn in Fig. l, thereby securinfv the striking face to the liaminer head. en the striking face be'- comes Worn ont, it and 'its jacket are removed from the head in any -convenient wey, the jacket being preferably gripped in a vice, and the hananer head being; twisted around until the lugs are leent and broken.-

ln the modification shown in Fi. 5 the lead slianlr 18p isv omned separate y from the striking Jtace 10, and tlie steel jacket 522g is formed oz increased lengti so that it` secures the elianlr and 'face together.. W'lien :made in this Way the face lo" can lie ronde of rar-7 liide or other soft material which is not suitable for fastening inge off tlie slianlr;

Widen. in use, tire lolowe strnclr ley tire llammer do not loosen the striking lace, as the lalovve only tighten the grip ofi the fastening loge in :the circumferential groove ci? .the need.

The lead striking face vvitli its elianlr and lugs is preferably cast into the steel jacket, and the projecting-parts 2B of tlie lugs are made tliiclrer than their inain portions, vvliicleare .encircled by 'the jacket, so tliat they will t better and more tightly in the groove. The steel jacket prevents the lugs from bending; outwardly.

What l 'claim is z,

l., A hammer head provided with a.

shoulder and a projectionnndercnt attire` shoulder, and a detachable striking tare provided with a socket which nts over the prey lill@ and vvliicli liao a series of longitndijection sott and nail rejecting lugs of relativel dncrlilep material which are locke said projection by impactagainst shoulder. 4

2. A. hammer liead provided with a iu.- jection, a circumferential groove, an o. shoulder havin a concave recess; and' a detachable striking, face rovided with ya ichts over the said projection, said socket having fastening which are :lient intmenga ement said groove by contact with the e said u, on the 7 roe lll)

bottom of `the seid recess end which been: against lie seid shoulder.

3. A hammer lieefl provided with e projection, a detachable striking. fece provided Willi e shenlr having e socket which fits over elle seid projection and which vlies farstening lugs for securing it to the hammer heeel7 enel a jacket encircling the saiol shank enel permiibring the said lugs to engage with lllelieecL said lugs being of relatively Sort and duciile material and being locked over lre seid projection. Y

A nommer head provided Wieh zr projeclion, e circumferential groove', and e shoulder; e detachable striking face provided wfch e, shank heaving e sockel', which. firs over the seid proje'orion enel which has esrening lugs for engaging' with rire Seidl Meme? gro-ove, end e jacket inclosing the said shank endbeering against the seid shoulder when the fastening lugs ere interlocked with the groove and projection.

5. A hammer heed provided with e projecrion, o, circumferential lgroove, and :r

shoulder; a detachable striking face provided l with a shank having e socket which lits over the said projection and Wliilch has farsteningI lugs provided with normally thickened end porionswhich engage with the seid groove, and e, jacket formed of herder materiel hen the said lugs and inclosing,1 the seid shank and. the mein portions of the seid lugs.

En testimony'wliereof ll have zriixeol my signeture.
